Gene expression profiling for the diagnosis and prognosis of acute myeloid leukaemia

Acute myeloid leukaemia (AML) is a heterogeneous disease covering a range of morphological lineages and differentiation stages, but also has number of recurrent chromosomal abnormalities and mutations associated with prognosis. Because of the defined molecular and cytogenetic features, AML has been a focus of gene expression profiling studies and identified differentially expressed genes in the different diagnostic and cytogenetic sub-groups. These studies have lead to the development of expression based classifications and diagnostic chips with further studies aiding prognosis and therapeutic choices.
